Execution
- 1Position the patient sitting with the hands on the waist and thumbs pointing posteriorly.
- 2Stand behind the patient.
- 3Stabilize the scapula and clavicle with one hand.
- 4Apply an anterosuperior force at the elbow with the other hand.
- 5Note deep joint-line pain, pop, crack, click, or anterosuperior shoulder pain.
Positive outcome
Pain or a click / pop deep in the shoulder or along the joint line is positive. Magee describes a pop or crack with anterosuperior pain as the humeral head slides over a torn superior labrum.

CommentOriginal anterior-slide values were strong, but later diagnostic work found limited utility for type II-IV SLAP lesions. Positive criteria must be deep shoulder pain / click rather than superficial discomfort. Use cautiously in mixed shoulder presentations.
Moderate Clinical Value
